Still water Vs sparkling water

Sparkling water: does it hurt or not? The choice between natural and sparkling water is always a source of doubt and discussion. Let’s analyze the situation of drinking water, with all the pros and cons of sparkling water in order to make an informed choice.

Carbonated water: sparkling water and natural effervescent water: what are the differences?
Carbonated water is mineral water particularly rich in carbon dioxide (also called CO2, or even carbon dioxide or E290). In some waters, it is naturally present, while in others it is added before bottling. This explains the presence of the so much loved or hated bubbles.


Natural Effervescent Water
It flows from the naturally rich source of bicarbonates and does not undergo any treatment: the natural effervescence combines with the mineral salts and other elements contained in the water.

Sparkling Mineral Water
It is natural mineral water with added carbon dioxide. Treatment does not change the nutritional characteristics of the water.

Calorie content
Water is the only natural 0 calorie drink, carbonated or natural.

The moisturizing power
Natural sparkling water, effervescent water and natural water hydrate in the same way, but this aspect will certainly not surprise you.

Refreshing effect: does carbonated water quench your thirst?
Those who, however, are convinced that carbonated water is more refreshing than the natural one can be disappointed: the sensation of greater freshness is only temporary.

It seems, in fact, that the belief that reduces thirst faster is due to the fact that the bubbles tickle the taste buds, but this is just a sensation of the moment. Another, similar, interpretation is that the bubbles stimulate taste receptors almost to anaesthetize them. Also for this reason the temporary sensation of freshness on the palate is greater.

Understand now why many people consider it more refreshing than the still water.

The fixed residue
It is not directly related to the type of water (natural, sparkling, or natural effervescent). However, it is important to know what it is. The fixed residue is a measure that allows measuring the number of mineral salts present in the water after the complete evaporation of the water that has been brought a temperature of 180° C. The higher this value (expressed in mg/l), the more minerals are dissolved in one litre. The advice is, for everyday use, to choose a water with a low fixed residue, with a value as low as 100 mg/l if possible

Pros and cons of sparkling or natural effervescent water


  1. Promotes digestion, as the carbon dioxide present stimulates the production of gastric juices
  2. give a greater sense of satiety than natural water and has the property of reducing appetite if drunk before a meal. In this case, we could say that it has a hunger-reduction action
  3. naturally sparkling waters generally contain more mineral salts, such as calcium, magnesium, potassium and sodium. However, these minerals are inorganic, so they are not easily assimilated. I disagree with the statement that I found in several articles on the web “sparkling water is indicated in those subjects that take few minerals with food.”
  4. according to some experts, the sparkling water is safer than the natural one because the added carbon dioxide should be able to limit bacterial replication
  5. the bubbles of carbonated water, consisting of CO2, promote gastric emptying and therefore can facilitate digestion


  1. It can cause abdominal swelling and gastric dilation, especially in those who already suffer from it
  2. carbonic anhydrite ruins tooth enamel
  3. it is not suitable for those suffering from stomach acid, gastroesophageal reflux, gastritis and gastric ulcers

A subjective choice
Beyond its organoleptic characteristics, which may be more pleasing to some and less to others, the choice of drinking sparkling water or natural water is subjective. My advice is always to choose the naturalness for which, natural or effervescent natural water. Moreover, it is always useful to listen to the reactions of our body. He always knows what’s good for us.
